This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACEJ16X25-10SB — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACEJ16X25-10SB in place of this model. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB
The AirTAC Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB is a double acting, adjustable stroke DIN-standard tight/compact air cylinder with a Ø16mm bore and 25mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ16X25-10SB (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB
The ACPJ16X25-10SB is a double acting compact cylinder with an adjustable stroke, built to DIN-standard dimensions on a hard-anodized aluminium body with an S45C hard-chrome rod. The -10 code gives a 10 mm trim window: a stop screw shortens the 25 mm extend stroke on site, so the usable range is 15-25 mm. At 0.5 MPa it pushes 100.5 N and pulls 75.4 N, rising to 140.7 N at 0.7 MPa, with a theoretical peak of 20.5 kgf at 1.0 MPa. The short ISO 21287-class body saves roughly 50% of the mounting length of an ISO 15552 profile cylinder, so it slots into tight jigs and guards. A fixed TPU bumper sits at both ends.
This model carries the optional -S magnet, so CMSE / DMSE reed or solid-state switches can be mounted for end-position sensing, and the B code gives a male rod thread on the 8 mm rod. Plan for about 60 N (roughly 6 kg) of real work at 0.5 MPa, which lifts about 5 kg vertically with a 2:1 margin. Note that the adjuster is a mechanical end stop only - on air loss the piston still drifts. The ACPJ family is discontinued; the current drop-in is ACEJ16X25, same bore, stroke and force class - confirm ISO 21287 mounting dimensions before swapping.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ16X25-10SB (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | 106 N |
| Max (@1.0 MPa) | 21 kgf | |
The ACEJ16X25-10SB produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB Is Used
Fixture clamping on CNC jigs
The 15-25 mm trim range lets a machinist dial in clamp travel on aluminium jigs, with 100.5 N at 0.5 MPa enough for light hold-down of small parts.
Carton push-off on small packers
A 25 mm stroke with a 10 mm window ejects cartons or blisters from a chute, and the -S magnet feeds CMSE switch signals to the PLC for position confirmation.
Ejector on electronics test benches
Male rod thread plus a Y knuckle drives a short push-off of PCBs from a test nest, with DMSE switches confirming each cycle at 30-500 mm/s.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB with the ACEJ16X25-10SB
Size both ways: if 100.5 N push at 0.5 MPa is marginal, step up to the 20 mm bore for 157.1 N; if the load is light, the 12 mm bore delivers 56.5 N at lower air use. The 10 mm window suits fixtures where the final position is tuned during commissioning. Match FA/FB flange or LB foot mounts and I/Y rod knuckles to the ISO 21287 face. For sensing, keep the -S magnet code. Order ACEJ16X25 as the current-production replacement.
Replacement checklist
- ✓ Current-production ACE → ACEJ16X25-10SB
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ16X25-10SB FAQ
At 0.5 MPa it pushes 100.5 N and pulls 75.4 N; at 0.7 MPa, 140.7 N push and 105.6 N pull; theoretical maximum 20.5 kgf at 1.0 MPa. Bore 16 mm, stroke 25 mm with a 10 mm trim window (usable 15-25 mm), rod 8 mm with male thread, M5x0.8 port, operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-500 mm/s, temperature -20 to +70 C, fixed TPU bumper both ends.
No - the ACPJ line is discontinued. The current-production drop-in is ACEJ16X25 (swap the P for an E), which matches the same bore, stroke and force class in the ISO 21287 family. Because the ACPJ was built to DIN-standard dimensions, confirm the ISO 21287 mounting dimensions before swapping. The ACEJ keeps the FA/FB flange and LB foot mounting family and the same optional -S magnet for CMSE / DMSE switches.
